aponeurosis is attached to the xiphoid and pubis. In the Gorilla, according to Soramer [491] the conditions are as in Man, but Bischoff observed no linea Douglasii. In the Orang, on the contrary, that line is well marked.
The rectus abdominis in the Chimpanzee has two origins as in Man, and four inscriptions run through it; its sheath is as in Man. In the Gibbon there are four inscriptions, and there are five in the Orang and Gorilla. These inscriptions really separate metameres, but they are not remnants of ribs.
The pyramidalis is frequently absent in the Chimpanzee, as in other Apes.
